BACKGROUND Intraductal tubular adenoma of the pancreas, pyloric gland type (ITA), is an infrequent intraductal benign lesion located in the main duct and large branch duct of the pancreas. The purpose of this report is to introduce seven new cases and to compare their clinicopathologic features and KRAS mutations to gastric-type intraductal papillary mucinous neoplasms (IPMNs) and intraductal t...

Despite a marked decline in incidence in the West and some decrease in the East, gastric cancer remains a significant cause of morbidity and cancer related deaths worldwide. The prevalence of gastric cancer is closely related to prevalence of Helicobacter pylori infection and shows wide geographic variation. Subsequent chronic gastritis, atrophy, and intestinal metaplasia are lesions that confe...

Schwannomas are generally slow growing asymptomatic neoplasms that rarely occur in the GI tract. However, if found, the most common site is the stomach. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and 60-70% of them occur in the stomach. Owing to their typical presentation as submucosal neoplasms, gastric schwannomas and GISTs ap...

Under the endoscopic observation with magnification endoscopy and narrow-band imaging, one of the novel findings in gastric neoplasms is white opaque substance (WOS), which is a manifestation of intracellular accumulation of lipid droplets. To elucidate the significance of this WOS formation, detailed lipid metabolism should be understood in gastric membranes. Recently, expression profiles of l...

Benign gastric tumours are infrequent. In Eusterman and Senty's (1922) series they amounted to about 0-6% of all gastric neoplasms. A higher incidence has been observed by other workers. Lockwood (1932) encountered benign gastric neoplasms in 45% of his cases, Eliason and Wright (1925) in 4.12%, Marshall (1955) in 4-8%, and Stout (1953) in 16-9% (the last high figure no doubt being due to selec...

BACKGROUND/AIMS Endoscopic submucosal dissection (ESD) has become accepted as a minimally invasive treatment for gastric neoplasms. However, the development of synchronous or metachronous gastric lesions after endoscopic resection has become a major problem. We investigated the characteristics of multiple gastric neoplasms in patients with early gastric cancer (EGC) or gastric adenoma after ESD...

Out of all the different types of neoplasms affecting the stomach, gastric carcinomas with Osteoclast-like Giant Cells (OGC) is one of the most uncommon. Although OGC are typically found in osseous neoplasms and tumors of the tendon sheath, few cases of extra-skeletal neoplasms with OGC have been documented. These typically involve organs such as the pancreas, gall-bladder, kidney, and breast. ...

abstract gastric cancer is one of the most common and most fatal neoplasms in human. its skeletal metastasis is less frequent, particularly when solitary. the objective of this article is to represent a case of solitary fibular metastasis from this cancer not reported before based on medline search.
